This patch extends the available device paths with a new device 'mdio'.
MDIO is the 'Management Data Input/Output' called interface which is
used to access an Ethernet PHY behind a MAC to change settings. The real
payload data path is not handled by this interface.
To address the PHY correctly on the MDIO bus, there is a 5 bit address
needed, which often can be configured via pins on the mainboard.
Therefore, the new introduced device has an 'addr' field to define its
address. If one wants to use a MDIO device in devicetree, the syntax is
straight forward (example):
device mdio 0x2 on end
As the MDIO interface is driven by the MAC, most likely this MDIO device
will be hooked in as a child device of the (PCI attached) MAC device.
With the new introduced ops_mdio a new interface is added to provide an
API for read and write access over MDIO.

The function pci_scan_bus had 3 post codes in it:
0x24 - beginning
0x25 - middle
0x55 - end
I got rid of the middle postcode and used 0x25 for the code signifying
the end of the function. I don't think all three are needed.
0x24 & 0x25 postcodes are currently also used in intel cache-as-ram
code. Those postcodes should be adjusted to avoid conflicting.

Currently, we're building support for all memory types into every board,
and letting the linker remove anything that isn't needed. This is okay,
but it'd be nice to be able to build in just what's actually needed.
This change adds options to specify both what is used and what is not.
By doing it that way, the default values don't change, but platforms can
start removing support for memory types that are not needed. When all
platforms (SoCs, CPUs and/or Northbridge chips) specify what memory
types they support, the defaults on the options to use a particular
memory type can be set to no, and the options not to use a memory type
can be removed.

We currently have two competing mechanisms to limit the placement of
resources:
1. the explicit `.limit` field of a resource, and
2. the IORESOURCE_ABOVE_4G flag.
This makes the resource allocator unnecessarily complex. Ideally, we
would always reduce the `.limit` field if we want to "pin" a specific
resource below 4G. However, as that's not done across the tree yet,
we will use the _absence_ of the IORESOURCE_ABOVE_4G flag as a hint
to implicitly lower the `limit` of a resource. In this patch, this
is done inside the effective_limit() function that hides the flag
from the rest of the allocator.
To automatically place resources above 4G if their limit allows it,
we have to allocate from top down. Hence, we disable the prompt for
RESOURCE_ALLOCATION_TOP_DOWN if resources above 4G are requested.
One implication of the changes is that we act differently when a
cold-plugged device reports a prefetchable resource with 32-bit
limit. Before this change, we would fail to allocate the resource.
After this change, it forces everything on the same root port below
the 4G line.
A possible solution to get completely rid of the IORESOURCE_ABOVE_4G
flag would be rules to place resources of certain devices below 4G.
For instance, the primary VGA device and storage and HID devices
could be made available to a payload that can only address 32 bits.
For now, effective_limit() provides us enough abstraction as if the
`limit` would be the only variable to consider. With this, we get
rid of all the special handling of above 4G resources during phase 2
of the allocator. Which saves us about 20% of the code :D

The `IORESOURCE_ABOVE_4G` flag was only explicitly set for our dummy
device that reserves resources behind a hotplug port. The current re-
source allocator implicitly extends this to all devices below the port,
including real ones. Let's make that explicit, so future changes to the
allocator can't break this rule.

Add option to resource allocator v4 that restores the top-down
allocation approach at the domain level.
This makes it easier to handle 64-bit resources natively. With
the top-down approach, resources that can be placed either above
or below 4G would be placed above, to save precious space below
the 4G boundary.

In theory, it could lead to endless loops even for compliant

We have this quirk in our tree since the introduction of L1-substate
support[1]. The way we searched for this capability was rather crude:
We simply assumed that it would show up in the first data word of
another capability.
As it turned out that it is actually a proper vendor-specific capa-
bility that we are looking for, we can drop some of the mystic code.
This was confirmed to work on the device that was originally used
during development, Google/Samus.

Move the `offset` parameter into pciexp_find_extended_cap(). If it's
called with `0`, we start a new search. If it's an existing offset,
we continue the search.

If we already encountered the last extended capability in the
list, we'd call pciexp_get_ext_cap_offset() with `offset == 0`.
So it also needs to check if the passed offset is valid.
As there were no callers of pciexp_find_next_extended_cap()
yet, pciexp_get_ext_cap_offset() was only ever called with
`PCIE_EXT_CAP_OFFSET`.

It's possible that some BARs are not got their resource successfully
mapped, e.g. when these BARs are too large to fit into the available
MMIO window.
Not assigned resources might be with base address as 0x0. During
global resource search, these not assigned resources should not be
picked up.
One example is MTRR calculation. MTRR calculation is based on global
memory ranges. An unmapped BAR whose base is left as 0x0 will be
mistakenly picked up and recognized as an UC range starting from 0x0.

coreboot uses TianoCore interchangeably with EDK II, and whilst the
meaning is generally clear, it's not the payload it uses. EDK II is
commonly written as edk2.
coreboot builds edk2 directly from the edk2 repository. Whilst it
can build some components from edk2-platforms, the target is still
edk2.

Looking into pciexp_get_ext_cap_offset() it seems a little hackish
and prone to endless loops. Either it should limit the loop or bail
out when pci_read_config32() returns 0xffffffff, meaning "Unsupported
Requests".
This commit fixes an endless loop when the queried PCIe device is
downstream of a legacy PCI bus which doesn't support extended config
space, thus pci_read_config32() will return 0xffffffff, for example,
the combination below with CONFIG_PCIEXP_SUPPORT_RESIZABLE_BARS
enabled.

existence (or absence) of a certain device on the bus, based on
whether or not a 0-byte write to an I2C address is ACKed or NACKed.
i2c_dev_detect() is implemented using the existing i2c bus ops transfer()
function, so no further work is needed for existing controller drivers
to utilize this functionality.

This patch introduces CONFIG_I2C_TRANSFER_TIMEOUT_US,
which controls how long to wait for an I2C devices to
produce/accept all the data bytes in a single transfer.
(The device can delay transfer by stretching the clock of
the ack bit.)
The default value of this new setting is 500ms. Existing
code had timeouts anywhere from tens of milliseconds to a
full second beween various drivers. Drivers can still have
their own shorter timeouts for setup/communication with the
I2C host controller (as opposed to transactions with I2C
devices on the bus.)
In general, the timeout is not meant to be reached except in
situations where there is already serious problem with the
boot, and serves to make sure that some useful diagnostic
output is produced on the console.

Section 7.8.6 of the PCIe spec (rev 4) indicates that some devices can
indicates support for "Resizable BARs" via a PCIe extended capability.
When support this capability is indicated by the device, the size of
each BAR is determined in a different way than the normal "moving
bits" method. Instead, a pair of capability and control registers is
allocated in config space for each BAR, which can be used to both
indicate the different sizes the device is capable of supporting for
the BAR (powers-of-2 number of bits from 20 [1 MiB] to 63 [8 EiB]), and
to also inform the device of the size that the allocator actually
reserved for the MMIO range.
This patch adds a Kconfig for a mainboard to select if it knows that it
will have a device that requires this support during PCI enumeration.
If so, there is a corresponding Kconfig to indicate the maximum number
of bits of address space to hand out to devices this way (again, limited
by what devices can support and each individual system may want to
support, but just like above, this number can range from 20 to 63) If
the device can support more bits than this Kconfig, the resource request
is truncated to the number indicated by this Kconfig.

Some PCIe devices have extended capability lists that contain
multiples instances of the same capability. This patch provides a
function similar to pciexp_find_extended_cap that can be used to
search through multiple instances of the same capability by returning
the offset of the next extended capability of the given type following
the passed-in offset. The base functionality of searching for a given
capability from an offset is extracted to a local helper function and
both pciexp_find_extended_cap and pciexp_find_next_extended_cap use
this helper.

Now that the console system itself will clearly differentiate loglevels,
it is no longer necessary to explicitly add "ERROR: " in front of every
BIOS_ERR message to help it stand out more (and allow automated tooling
to grep for it). Removing all these extra .rodata characters should save
us a nice little amount of binary size.
This patch was created by running
find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';'
and doing some cursory review/cleanup on the result. Then doing the same
thing for BIOS_WARN with
's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi'

List of changes:
1. Create Module Type macros as per Memory Type
(i.e. DDR2/DDR3/DDR4/DDR5/LPDDR4/LPDDR5) and fix compilation
issue due to renaming of existing macros due to scoping the Memory
Type.
2. Use dedicated Memory Type and Module type for `Form Factor`
and `TypeDetail` conversion using `get_spd_info()` function.
3. Create a new API (convert_form_factor_to_module_type()) for
`Form Factor` to 'Module type' conversion as per `Memory Type`.
4. Add new argument as `Memory Type` to
smbios_form_factor_to_spd_mod_type() so that it can internally
call convert_form_factor_to_module_type() for `Module Type`
conversion.
5. Update `test_smbios_form_factor_to_spd_mod_type()` to
accommodate different memory types.
6. Skip fixed module type to form factor conversion using DDR2 SPD4
specification (inside dimm_info_fill()).
Refer to datasheet SPD4.1.2.M-1 for LPDDRx and SPD4.1.2.L-3 for DDRx.

This patch changes the sc7180 boards to use the new common MIPI panel
framework, which allows more flexible initialization command packing and
sharing panel definitions between boards. (I'm taking the lane count
control back out again for now, since it seems we only ever want 4 for
now anyway, and if we ever have a need for a different lane count it's
not clear whether that should be a property of the board or the panel or
both. Better to leave that decision until we have a real use case.)
Also, the code was not written to deal with DCS commands that were not a
length divisible by 4 (it would read over the end of the command
buffer). The corresponding kernel driver seems to pad the command with
0xff instead, let's do the same here. (Also increase the maximum allowed
command length to 256 bytes, as per Qualcomm's recommendation.)

All boards that are trying to use MIPI panels eventually run into the
problem that they need to store physical parameters and a list of DCS
initialization commands for each panel, and these commands can be very
different (e.g. a large amount of very short commands, a few very large
commands, etc.). Finding a data format to fit all these different cases
efficiently into the same structures keeps being a challenge, and the
Kukui mainboard already once put a lot of effort into designing a
clean, flexible and efficient solution for this. This patch moves that
framework into a common src/device/mipi/ library where it can be used by
other boards as well. (Also, this will hopefully allow us to save some
duplicated work when using the same panel on different boards at some
point.)
